Abstract
The objectives of this pilot study were to (a) develop and test an instrument and methodology to assess subjectively cleanroom garment comfortand (b) evaluate comfort and particle containment of a traditionalfabric hood and complete coverage hood with remote breathing device. A female subject wearing coveralls, boots, gloves, and either a fabric or complete coverage hood assembly used a subjective comfort instrument to identify garment wearing sensations, thermal comfort, and perceived physical state. The subject was able to distinguish between the level of thermal comfort of the two hoods with the complete coverage hood being more comfortable than the fabric hood. She identified heaviness as a sensation that differed between the two hoods; the complete coverage hood was felt to be heavier than the fabric hood. The subject was less likely to feel energetic, interested, and attentive while wearing the complete coverage hood Early evidence indicates that a human perception approach can provide useful information on cleanroom garment comfort. Recommendations are made for refinement of the comfort assessment methodology. The complete coverage hood was more effective than the traditional fabric hood in containing particle contamination from face and head.
